The hydraulic concentric bearing incorporates the release bearing and the slave cylinder in a single assembly.

The hydraulic concentric bearing completely encircles the transmission input shaft. In operation, the piston movement causes the bearing to move in a straight line direction.

The hydraulic concentric bearing is serviced as an assembly only. The release bearing portion of the assembly is permanently attached to the piston. The hydraulic lines are also permanently attached.
